Low Temperature Synthesis of ZrO2-TiO2 and SiO2 Glass from Zr(NO3)4, Ti(OC4H9)4 and Si(OC2H5)4,

Abstract

Using Zr(NO3)4.5H20 as one of the starting materials, glasses in the system ZrO2-TiO2-SiO2 were prepared by the sol-gel method. The influence of various factors on the gelling properties of the system, the variation of viscosity with time of the reaction system, the different environmental conditions on the unity of gel mass and the effect of heat treatment conditions on the final results have been studied in detail. In order to investigate the change of dry gels during heat treatment, DTA and IR absorption spectroscopy analysis were also made. On the basis of the above studies, small transparent glass pieces were obtained, and some problems were discussed, such as the method of adding water into the reaction system and the function of Zr(4+) ion in the glass, etc. (China Translations).
